I think "Atmospheric electricity" is the regular diurnal variations of the Earth's atmospheric electromagnetic network or, more broadly, any planet's electrical system in its layer of gases.Two gases make up the bulk of the earth's atmosphere: nitrogen (N2), which comprises 78% of the atmosphere, and oxygen (O2), which accounts for 21%. Various trace gases make up the remainder.
